chanari Posted December 21, 2005 Report Posted December 21, 2005 Hello Modicon is completely new to me. I am trying to download PLC program from Modicon PLC(984-A145 CPU). I am using Modicon workshop software. I am wondering what kind of cable do I have to use to get the communication working? Because I tried using a seriel cable(9 pin both ends) and I could not able to establish communication. Thanks in advance. Quote
